Answer:
3.Subtitute in the two values of radius and height centimeters.
a = 10(25) * pi + 2(25) * pi
a = 20pi + 50pi
a= (3.141(250)
a = (3.141)(50)
a = 945
therefore the surface area of thetumbler is 942cm²
4.square inches of paper required.
curved surface area
d20cm r=10cm 1 18cm.
3.14 * 10 * 18
=565.2cm²
5.
a = 4pi * r ^ 2
a = 4 * 3.14 * 400
@4x1256
a = 50 24 mm
the su face area of the tennis ball is 024mm
